Functionalized Polymer-Capped SnO 2 Nanoparticle Electron Transport Layer for Efficient Perovskite Solar Cells
Abstract
For the last decade, perovskite solar cells have been in rapid growth, highlighted as a representative next-generation solar
cell. Although SnO 2 is suitable as the electron-transporting material of perovskite solar cells, there also have been some
obstacles in the formation of uniform and thin layers of SnO 2 on the uneven FTO substrate. In this work, we investigated
polymer-assisted fabrication methods to achieve conformal coating of SnO 2 nanoparticles on rough FTO substrate, fi nally
leading to improved performance of perovskite solar cells due to enhanced coverage and optimized electron-transporting
property. As a result, we fabricated an effi cient perovskite solar cells with a power conversion effi ciency of 24% by employing
polymer-capped SnO 2 nanoparticles as electron-transporting layer.
